It's the frequency of letters and numbers being formed back to front, and the being able to spell v. well out loud but not so well when written down that continues to puzzle me.
Hello, don't know if this will be helpful or not.
I have a five year old (and two older) but summer born so year 1.She is an excellent reader.She has a reading age well in excess of her years and loves books.
However she has mild coordination issues so finds writing a real physical effort.She still reverses letters and numbers because, I believe, her "physical memory", ie the movement her body has to make to form letters and shapes is well behind her visual memory.
Her auditory memory is very good.She too can spell words gleefully out loud but would not recall them in full or write them correctly.
I believe it is a developmental issue.She was my latest to be nightime trained, took ages to hop and that kind of thing(not that it matters of course) and still uses a knife and fork in a very peculiar way.
If she is still this way coming out of KS1, then I will seek an assessment for dysphraxia but my gut instinct is that it won't be needed.This side of her development is just lagging behind the others.
Incidentally my middle child is not an outstanding speller.She's not dreadful but in this area, she lags behind her success in other areas.Nonetheless she is overall above average academically and at a very selective grammar.Lots of very bright people are not great spellers.
She cannot spell out loud words as successfully as she can write them and hates being tested verbally for spellings.
This is just an outworking of her strengths/learning style.
So...sorry if I went on.I think I am just saying, in my opinion, it is too early to worry seriously about this and children do not develop evenly in all areas.
